By Karl-Klaus Dittel, Matthias Rapp

The scope and value of hip fractures is sort of incomprehensible. With an international broad occurrence of with regards to 2 million instances in line with 12 months, those fractures pose a frightening problem to our skill to impact and deal with this epidemic.

Basics for operative remedy of proximal and distal femur fractures: transparent surgical indication, brief making plans and education < 24 h, complete weight bearing osteosynthesis, early mobilisation and physiotherapy.

In complete shape the e-book offers using a in the meantime good put in implant (DMS) for osteosynthesis process within the peritrochanteric area. The ''double dynamic'' stabilization (sliding tongue precept and perspective tailored contoured healthy) ability a cutting-edge fracture therapy method. it's a convincing substitute to accomplish a organic osteosynthesis on the femur. The process comprises an infinitely adjustable, versatile perspective, dynamic plate with a tubular distal part.

3 shows the groups of trabeculae in the hip joint region. Three groups can be identified in the proximal femoral portion. The trabeculae that are primarily under tensile stress curve medially below the greater trochanter to the fem- Fig. 1.

The medial, main trabeculae are under stress from pressure, and form a second, triangular group which extends from the cortex at the level of the lesser trochanter to the femoral head.

They represent a continuation of the acetabular trabeculae. The secondary, lateral stress trabeculae stretch peritrochanterically from the calcar femorale and the lesser trochanter to the greater trochanter, by-passing Ward’s triangle [8]. The widely used classification of fracture of the medial femoral neck by Pauwels is based on the angle between the fracture line and the horizontal, and differentiates between Pauwels I, II and III fractures (Fig. 4). 5 shows a fracture of the medial femoral neck of the Pauwels I type pre- and post-operatively.
